The research work considers and analyzes the problem of control valve failure in case of shaft-gear break during normal operation.In order to identify typical deviations and causes of failure of the electrically driven valves, the amplitude-frequency spectra of the current signal taken at one or more phases of the electric motor were analyzed.The m
Language in the Context of South African Workplace Discrimination Law

Use of Multi-Anionic Sodium Tripolyphosphate to Enhance Dispersion of Concentrated Kaolin Slurries in Seawater
This research aims to analyze the impact of sodium tripolyphosphate (STPP) as a rheological modifier of concentrated kaolin slurries in seawater at pH 8, which is characteristic of copper sulfide processing operations.The dispersion phenomenon was analyzed through chord length measurements using the focused beam reflectance measurement (FBRM) techn
Cultural significance of locusts, grasshoppers, and crickets in sub-Saharan Africa
Abstract Background In sub-Saharan Africa, there is a wealth of information about insects which is often only orally available.The purpose of the study was to remedy this shortcoming and make an overview of how orthopteran species are utilised, perceived and experienced in daily life across sub-Saharan Africa.Method Ethno-entomological information
Optimal Linear Precoding Under Realistic Satellite Communications Scenarios
In this paper, optimal linear precoding for the multibeam geostationary earth orbit (GEO) satellite with the multi-user (MU) multiple-input-multiple-output (MIMO) downlink scenario is addressed.Multiple-user interference is one of the major issues faced by the satellites serving the multiple users operating at the common time-frequency resource blo
